T h m it may concern: The novelty of the invention lies mainly in 50 Beit known that I, WALTER H. PUMPHREY, utilizing the outer end of theordinary syr a citizen of the United States of America, and inge-pipeand adapting it to coact with a bulba resident of New York, in thecounty and like sleeve in the production of a whirling- State of NewYork, haveinvented certain new spray discharge.

The liquid in passing through these tubular den deflection froma straight-away course the liquid is given a whirl and passes spirallythrough the bulb-like sleeve-section. In being thus acted upon theliquid is converted into whirling spray, which in its discharge assumesa globular form.

Having therefore described my invention, what I claim as new, and desireto protect by Letters Patent, is-

In a syringe, the combination of a jet-tube provided adjacent to itsouter end with one ing the end of the tube and its branched outlets andproviding a curved wall against which the liquid is directed.
